The video maker seemed to be a newbie at using a Drill Doctor. After using one for years, I find its strength is the little bits like 5/32" to 5/16". Anything larger than 5/16" is pretty easy to free hand with grinder with a bit of practice. The Drill Doctor excels at the smaller bits in my opinion.

I have had no luck with the Drill Doctor at all. I bought the 750x and have carefully followed the instructions with little success. The tolerances between the chuck and the body are too lose. Even with very careful use the results were hit and miss.
A useful looking grinder is the SRD type:

I can't see that the chuck would be hard to make and the cup wheels are readily available in CBN so they will have a decent service life. People who use these seem to be very happy with their performance, especially for smaller bits which other sharpening systems struggle with.
